GEORGE W. BANKER, OF BROOKLYN, EW YORK.

MANUFACTURE OF OIL.

SPECIFICATION forming part of Letters Patent No. 255,096, dated March 21-, 1882,

' Application filed December 12, 1879.

To all whom it may concern Be it known that I, GEO. W. BANKER, of Brooklyn, in the county of Kings and State of New York, have invented new and valuable Improvements in a Composite Oil for Lubricating, &c., of which the following is a specification.

Since the introduction of petroleum and its products for lubricants, leatl1er-(lressing, and other purposes, attempts have been made to combine such oils with caster-oil; but no satisfactory nor inexpensive mode of permanently eombiningcastor-oil with mineral oils has here tol'ore been discovered and made known to the public.

My discovery consists in the use of corn-oil for combining eastor-oil with heavy oil produced from petroleum or paraffine in nearly equal proportions.

What I claim is- The herein-desciibed composite oil, composed. of caster-oil, corn-oil, and heavy oil produced from petroleum or paraffine oil, in nearly equal proportions.

GEO. W. BANKER.
